Patented Jan. 12, 1932 was it JOHN A. SCI-IAUSS, or NOBWALK, 0111c, assreivjcn TO THE COMMERCE GUARDIAN 'rnus'r & SAVINGS BANK, AS, TRUSTEE, or ToLEno; OHIO, A CORPORATION or OHIO I oomronr' err-em Application filed August 19, 1929. Serial No. 386,909.

Fig. 2, looking in the direction of the arrow and ing the stirrup and trigger 'as released for free positioning of the seat-and back unit relatively to the base and arm unit of the chair.

Legs 1, 2, carry fixed therewith rectangular 7 frame 3 as a base from which rises a pair of wardly from this brace 5, side portions of the frame 3 have fixed'therewith blocks 6 carrying a straight line series of upwardly open notches 7 transversely in aligned pairs.

Seat 8 is mounted between the arms 4 and has rigid therewith back 9. This second unit 8, 9, is herein shown as disposed between the arms 4 and provided with trunnions 10 laterally protruding therefrom in similar are series coacting as to the central trunnions,

with the central notches 7 when the support is in upright position. As relative rocklng between the first and second unit occurs, thesetrunnions enter into or recede from the re- H spective notches 7 in providing a rocking bearing between the pair of units.

The sides'of the seat 8 have pivot pinsll for links 12 having fastening means 13 assembling transverse block 14. These straps or links 12 and block 14 comprise a stirrup normally tending to swing downward. In seti up position of the seat 8 and back 9, this stirrup 14 abuts ledge 15 of the base and provides a rigid lock in holding the structure as a fixed chair structure.

Externally the chair to all appearances is that of a common rigid chair having uphol- Q stery seat 16, overstufled seat cushion 17 and Fig. 4 is a fragmentary detail v1ew show'-.

arms 4 rigid with this base 3. The base 3 I is shown as having forward side connectmg brace 5 fixed with the base frame. Rear ,thereof of a metal.

upholstered arms 18 and upholstered back 19. However, to convert this apparently fixed chair intoa comfort chair it is only necessary to pull the back 9 slightly forward as'a rocking action for the back-and seat unit relatively to the base and arm unit.

This pull forward pullsthej stirrup portion 14 clear of the'ledge 15 and causes notch 20 in the stirrup 12, l4,toride past" nose 21 of trigger bar 22 having terminal trunnions 23% directly pivoted in the base 3. This rocking action for the chair brings thetrigger nose 21 into notch 26 ofthe stirrup, so that ina rearward rocking of'the back'9, thestirrup port1on 14 rocksthe bar 22 and the porti0-nf65 14 is swung rearwardly clear of the ledge 15 to ride onsurface 24. This will permit free rocking'of the unit 8, 9, relatively to the unit 3, '4. The trigger bar 22 is counterweighted and as soon as free of the bar 14, the bar 227.70 rights itself by engagingstop 27 by its recess.

, In practice, as a comfort chair, the tilting may be justto adesired angle for rest. At

such position or even at an oscillating posiz's tion, there is stability for quiet and substantial operation, in that the blocks 6 and trunnion 7 may be of wood, as well as the stirrup portion 14, and the trigger, thus leaving -,only the strips 12Lasrthe assembly meansrsn To bringthe chair, to a maintained or rigid set up position, the chair back 9 may beswung forward to permit the bar 14 to ride toward the trigger 22 and upon the ledge: 15, the trigger bar forming an abutment against which the stirrup falls to determine the ledge abutting relationship. From this positiorn the rearward rocking of the back 9 causes the stirrup portion 14 to lodgegQ against ledge 15.. The position of rest for the trigger 20, 21, is determined by the stop 27 coactingwith the recess 28'therein.

What is claimed; and it is desired to secure by Letters Patent'is: 0

1. In a chair, a base, a seat rockable thereon, a member carried by the seat swingable upon seatgmovement, a. ledge carried by the base a-butted by said member at one seat position to maintain said seat against rockingfl fi rearwardly, said member swingable from the ledge upon forward seat movement, and mechanism carried by the chair and operable on moving the seat forwardly a predetermined distance to swing the member clear of the ledge upon rearward movementof the seat.

2. A chair comprising a base unit,.a seat unit rockable thereon, a stirrupmounted on the seat unit and swingable therefrom,

a ledge carried by the base unit said stirrup swingable to abut the ledge to resist one way rocking movement of the seat unit with movement the other way unresisted, said stirrup movable away from ledge abutting position'upon movement of the seat unit in the unresisted directiomand a trigger carried by one of the units to engage the stirrup when moved from the ledge a predetermined distance'and'to carry said stirrup clear of the ledge in movement'of the seat unit in the opposite direction.

3. A chair-comprising a base unit, a seat unit, a rocker providing bearing therebetween, mechanism interacting between said units permitting free forward movement of said seat unit while restricting rearward rocking movement thereof, and control means operable by movement of one of the units to coact with said mechanism to permit freerocking movementin both directions.

4. A chair comprising a base unit, a seat unit rockable thereon, said units having a maintainedposition and a free rocking position, and mechanism interacting between said units comprisinga swingable member on the seat unit, a ledge to be abutted there- 'by on the base unit in the maintained position, and means coacting with the swingable member during movement of the seat unit to carry the swingable member beyond the ledge for the free rocking position, said swingable member operable by seat unit movement for determining the position.

maintained position to move said member clear of theabutment, means engaging the member as moved clear of the abutment to cause said member to clear the abutment on the backward movement of the seat unit for permitting free rocking movement of said seat unit on the base unit.

6. A chair comprising a base unit and a seat unit rockable thereon, control means maintaining said units against free movement therebetween and operable by a normal forward movement of the seat unit from maintained position to release said means to permit free rocking movement of said seat unit on the base, and reset means operable for returning the control means to holding position upon a second movement beyond normal forward rocking movement.

In witness whereof I affiX my signature.
